uImage: return base load address (Hollis Blanchard)

Return the base address at which the image was loaded so that callers may keep
track of currently occupied guest memory.

This will be required by the PPC 440 embedded code to avoid hard coding a
device model/initrd location.  Other users of this function could make use of
this parameter to avoid hard coding these locations in the future too.
